When renting out a part of your home, there are two questions that *everybody* misunderstands and gets flat out wrong, resulting in no allocations occurring, or blatantly wrong allocations occurring.
- The percentage of business use is ONE HUNDRED PERCENT BUSINESS USE of the 20% (or whatever) of the property that was rented out.
- The number of personal use days is *ZERO* days for whatever percentage of the property you are renting out.
